Assembled with vanilla sponge cake, lemon blueberry swirl whipped cream, and lemon cream cheese buttercream, this vertical cake screams celebration. It’s soft and light with bright refreshing flavors and an impressive aesthetic. Who can resist?
You’ve been requesting a challenging dessert recipe and after 6 failed vertical cakes and 12 total recipe tests, I admit that this one is tough! But I’m happy to share my recipe fails and successes with you so you can get the recipe right on the first try. I know you can do this and will be proud to check this baking bucket list recipe off your list!
Our eyes are used to seeing horizontal layer cakes, so when you first cut into a vertical layer cake, you’re instantly impressed. They’re ALWAYS a crowdpleaser! But what are they and how can we make one?
Vertical cake is just that: a cake with vertical layers. Instead of stacked layers like traditional layer cakes, vertical cakes are actually made with a cake spiral. When you cut into the cake, that spiral displays as vertical layers. You assemble the cake spiral with a sponge sheet cake. Roll the sponge cake into a cake roll when it comes out of the oven. Once cool, unroll it, cut it into 3 long strips, then top each with whipped cream. Roll the strips up, connecting the end of the first rolled strip with the next. Turn the cake upright and decorate with frosting as you would any other layer cake.
There’s a few more steps along the way, but that’s the basic rundown!
Before we get into the nitty gritty, let’s watch this vertical cake come together:
A successful vertical cake must begin with a sturdy sponge cake. This is where all 6 previous recipe tests went horribly wrong. I tried separating the eggs, cake flour, all-purpose flour, baking powder, no baking powder, deflating the batter, creaming the butter, melting the butter, no butter… honestly I could keep going on about all the mistakes I made. If the sponge cake is too fragile, the vertical cake will collapse. If the sponge cake is too firm, it won’t roll up. Take it from me– follow this sponge cake recipe to the letter.
Forceful mixing will deflate this airy sponge cake batter. Be gentle—it needs volume!
No time for cooling! When it comes out of the oven, immediately invert the warm cake onto parchment paper or a thin kitchen towel dusted with confectioners’ sugar. Gently roll the cake up with the parchment/towel. Let it cool in the rolled up shape so when it’s time to roll it up with the whipped cream filling, it’s already “familiar” with the rolled up shape.
The lemon blueberry swirl whipped cream combines homemade lemon blueberry sauce and whipped cream. If desired, feel free to use your favorite blueberry (or any flavor) jam to replace the homemade lemon blueberry sauce. The sauce must completely cool before you mix it into the whipped cream, so I recommend making it ahead of time or as the cake cools. You need blueberries, lemon juice, cornstarch, water, and sugar. Cook it on the stove, cool it completely, then fold into lightly sweetened whipped cream. For the whipped cream, you need heavy cream and a touch of confectioners’ sugar.
This whipped cream would be unbelievable with pound cake or sandwiched between choux pastry, too! Or our not-so-sweet whipped frosting would make a great alternate filling for this cake.
If you think about it, the cake should only be about 3.5 inches tall, right? The strips actually stretch and bulk up as you roll them with the filling! So after you top the cake with cream cheese frosting, the cake ends up being about 5 inches high by about 6 inches wide.
Just like any layer cake, this lemon blueberry vertical cake needs a frosting decoration. Whip up a simple lemon cream cheese buttercream by combining brick cream cheese, butter, confectioners’ sugar, lemon juice, and vanilla extract. A bench scraper and small offset spatula are handy for decorating. Some of the whipped cream exposed on the top of the cake will mix with the buttercream, creating beautiful random swirls of purple. This cake is gorgeous on both the inside AND outside.
One last step: refrigerate the decorated cake for at least 30 minutes before serving. This prevents the cake from squishing too much when you slice it.
Looks like a regular cake, right?
It’s what’s on the inside that counts. 🙂
This recipe yields one vertical cake, about 5 inches tall and 6 inches wide. For best results, follow the recipe carefully and read through the directions before beginning.
